In the framing of a deck or building, a rim joist is the final joist that caps the end of the row of joists that support a floor or ceiling. A rim joist makes up the end of the box that comprises the floor system. The header is to a rim joist what the top or bottom Wall plate is to an end stud. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rim joist」の詳細全文を読む スポンサード リンク
